To all whom it mag concern Be it known that IQELIsnA F. BnAvnns'rocK, a citizen of the United States of America and resident of Holyoke, in the county of Hampden and State' of Massachusetts, have invented certain newandnsean Improvements in, Weft Binding and severing Devicesf'or Looms, of which the following is a full, clear, and exact description.

p This invention relates to improvements in automatic looms in which bobbins, from supplying means, are per odically delivered into the shuttle, causingfexpulsion of the shuttle bobbin from which the thread emloom has'become' exhausted. In looms of this kind,'as well known, there is employed a so-called f eeler which has a cooperative ==lpoint adjacen vi and; to sever the said ere-amen the tie is to be replenishedj with a freshsbob bin,-holding the en dflportionof the Weft 69 relation near one ofthe shuttle boxes with the more or less nearly thread filled bobbin so that when the thread shallhave become exhausted to the extent that but very little Oil tile thread remains on the bobbin, it will be instrumental in causing the rocking of the shaft'which aetuatesa means for the dischar e of the fresh-sfilled, bobbin from the bobbin supply into the shuttlafiwhile the latter is in the shuttle box,and an ex: pulsion from the shuttle of the exhausted bobbin. a a s Under this invention the loom is equipped with a device located onthe-maehine adja-" cent the lay a operable to both tempomay. bind th shuttlefsuppliedweft alt 0X1 e mouth .01: the shnttl B uti- ' and theloom is alseleijuipped with a second j'device, mounted adjacent the lay and between the ends of the shuttle box, operable 'to temporarily bind the portion of the weft,- between the first binding and cutting device and the point where the weft emerges from. the eye of the shuttle-, near one'end'pthereof almost simultaneously cutting the weft, near where it is held. By theabove-mentioned,

Fig. 11 is a. sectional elevation slmwiug a detail of construction to be hereinafter referred to. Figs. 1&2 and 13 are cross sectional views through the jaw portions of the second binder and cutter with the relatively movable parts thereof shown is opened and closed positions. Fig. 14 is a view designed to more clearly illustrate the yielding character of an element comprised in the jaw opening and closing means of the second binder and cutter. It is to be stated that the elevation views, Figs. 1, and -l are as seen looking inwardly from about the line .r-a while the elevations, Figs. 9 and 10 are as would appear looking from said section line ai-ai outwardly.

Similar characters of reference indicate corresponding parts in all of the views.

The feeler controlled rockshaft is indicated at in Figs. 3 and -l. It carries a. curved lever arm 13 which by its bifurcated cud engages the projecting: stud rt on a leverlike member (I which is pivoted at I) for roclting movementin a vertical plane. The said member G has at an intermediate part thereof a ln'n'izontal inwardly projecting stud-like memhero carrying as a rigid right annular extension thereof a slottcd part C Tl represents the bobbin feeder coiiperativo with the rotary pochet provided bobbin huldr! or magazine TC intermittently rotativc to successively brine down fresh bohbins to proximity to the shuttle box I on the lay 1. An artimllation is made between the oscillatory appliances C, C and the pivoted angular shuttle feeding element I) through the element H, which by pivot (Z is hung: to and carried by the depending: arm of the angular levenlike member D, and by stud c has an engagement in the slot or aperture in the offset extension (l which is movable as one with the lever-like 1nen1- her C.

G represents a curved or angular arm which is made as one with the lever-like InemherC and extends upwardly and rearwardly toward the path of the shuttle across the iay. The extremity of this arm (i has, rigidly connected therewith, but in slight separation therefrom, a block or plate (i and the extremities of the arm proper and the supplement plate G are formed bifurcatcd or recessed, as indicated at f, to form both binder and cutter jaws.

H represents a lever-like member connected by pivot g on the arm G and having by menace the stud and slot construction indicated at h the swinging movement thereof limited, and the said member H has a projection z adapt ed to be contacted against by the lay when under the operation of the feeler-controlled roclzshaft the arm G shall have been swung to within the range of the final or beating up portion of the movement of the lay. The member H is of bifurcated form as indicated in the upper portion of Fig. 5, whereby the blades j and 7' are produced, these blades straddling the block or plate-like-portion Gr the blade j being for cuttin g -and enacting, shear-like, with a knife or blade i on the jaw end (if the arm G,While the blade serves in conjunction with the blunt corner I; of the block or plate G as a binder so that when the two blades are simultaneously moved to their closed position there will first be a binding of the weft by the parts y" and G, and a cutting of the weft near the point of the binding by and between the blade j and the portion of the jaw G which may advantageously be provided with a hardened shear section j. The corner is of jaw portion of the plate G is understood as blunt, as seen in Figs. (9 and 7, and it is perceived that the binding edge is is higher than the edge of the shear portion of jaw G, whereby the weft will be bound by blades at the point, L before it is cut by the blade In Fig. 3, the above described parts (most of which are as already known and in use on a loom) are represented in their normal position, that is when the loom is running with a full bobbin, the binder and cutter jaws, however, l'leing understood as closed, and in wait binding condition.

When the bobbin becomes exhausted of thread, through the controlling action of the trader, a rocking of the shaft A. is efi'ected and the curved arm 13 is swung from the msition, Fig. 3, to that indicated in Fig. 4, causing through the articulated parts C, (l and ll the swinging, movement of the bobbin feeder D for the down feeding of the new bobbin into the shuttle and the expulsion of the exhausted bobbin therefrom. At this time the arm (l is carried inwardly so that the bifurcated jaw ends thereof embrace or straddle the weft extending from the shuttle of the practically exhausted bobbin to the selvage. and almost at the same time by the engagement of the stud with the lay the double jawsf and j are closed, shearlike, the one to bind, and the other to cut the weft at a point adjacent the mouth of the shuttle box and between the latter and the selvagre. Then, almost immediately, and on theluiriginp, of the fresh bobbin into the shuttle, the l'cclcr controlled rockshaft is effective to restore the connections and the arm fl above described to their normal position,- Fig. 3,-the jaws remaining closed l on 1 comprising apart 'J made with u slideiva in which the slide burdi ismovable reciprocatory motion in. :i straightahorizontzil j I j line at right angles to the line of projection of'flthe shuttle, sncl'one whichis coincident with the part ofthe s'huttlerbox in which an ineness until the last fedbobbinalso beeomes ex.-

As represented "in Fig. 11, the slide bar K carrying the oscillatory device comprising the blades and 0" at opposite sides of such slide bar, slot o in which a spiral spring o is proyided in compression, one end of such spring bearing against the end of the slot and the other end bearing againsta pint which is passed,transversely through the slide bar at the opposite end of its slot and projects into and is movable in an are shaped slot 11 in the oscillatory blade X comprising, device,-tliis provision being e ective for maintaining the blades 0, o in the positions to which they may be thrown, either opened or closed, and until such positions shall be reversed as desired for the proper operation of the mechanism.

It is understood that thespringmts a pressure against the pm o to keep it in either of the extremities of tl1e slot, any displacement of the spring from its retain- -ing position necessarily requiring that it be moved past the central or dead center portion of the slot boundary.

Atthe time when the feeler controlled rockshaft is swung to carry the'articulated members between such shaft and the bobbin feeder to the position shown in Fig. i, the element H, in such position being repre sented in Fig. 10, the open jaw slidable device K, o, o is projected so that such jaws pass into and through an aperture to in the side of the shuttle box between the ends of the latter andmore or less into an ape ture w in the side of the shuttle, as represented in Fig. 10.

The weft of the expiring bobbin is understood as lying, as usual, along the outer grooved face of the shuttle so that upon the engagement between the abutment o and the lay, causing the movable jaws 0 and 0 to assume their closed positions. the Weft will be out by the blade 0, ci'iacting with the sharp cornered portion 0 of the slide bar K, after being bound by the blade 0* which courts witlrthe blunt cornered portion 0 of the slide bar K, as represented in Fig. 13.

So soon as the feeler controlled shaft A is swung to its normal position, whereby the element H is moved out of engagement with the stud p which projects from the lever N,

' the slide bar and its closed jaws are retired in a line at right angles to and away from the shuttle carrying the bound and of the weit therewith and out of the line in which the weft is carried in the weaving action,-- the jaws during such witl'idranal remaining, closed so that the short piece of the wait hold by the binder will be carried forwardly to a point at which it will be without lia bility of becoming entangled with the wait at of the new supply to be "further woven into is made with a longitudinal the fabric being made in the loom. lt'will be dropped on the commencement of the next inward projectirin of the slide bar, when stud t impinges cam lip ll which is incapable of upwardly yielding.

The first cutter and binder savers the weft as near the selvage as practicable and binds, temporarily, the end adjacent the out but which is toward the shuttle; while such end is held by the binder appurtenant to the first cutter, a portion of the weft farther outwardly located is severed by the second cuttor after the end adjacent the second cut and still farther outwardly in the direction toward the outer end of the shuttle box is 30v bound and retained during the time the next bobbin is supplying the loom and to be released and permitted to drop, free and clear away from the line of shoot of the weft being woven into the cloth. 5

I desire to be understood that the first cutter, carried on the swinging; arm G, cont prising the shear plate 7' on the jaw end of said arm G and the shearblade.3 enacting therewith, and the fer-tor shaft operated connections for positioning the arm G and the means for causing the closing of the cutter blade j and for causing the o ening thereof on thenext succeeding inwarr movement of the arm, are as already well known, and ex tensively used in automatic looms,--but I have made the extremity of the arm G a support for the part G and the blade j whichconstitutes the binder, and have so combined or united the newly provided binder blade with the cutter blade 5? that by moving in unison with the latter no new or added means is required for the opening and closing of the movable element of the binder.

The parts G 7' forming the first binder provide that the weft out beturon the mouth of the shuttle box and the salvage will be suitably held to be in proper taut condition, and in proper line to be subject to the action thereon of the novel, herein termed second, binder, and cutter which has its location opposite an intermediate part of the shuttle box and the shuttle therein.
